The enforcement of the penalty would likely allow for possible ejections, which would be subject to replay review. The NCAA ruling mandates ejections for contact made with the crown of the helmet or to the head or neck area of a defenseless opponent.An example of such a penalty came on Monday night as Pittsburgh Steelers wide receiver JuJu Smith-Schuster delivered a helmet-to-helmet blow to Cincinnati Bengals linebacker Vontaze Burfict, who was deemed a defenseless player on the play. Burfict was carted off and placed in the concussion protocol, Smith-Schuster received a one-game suspension for the hit.
